We can't control the weather but we can teach about it. The Eco-Celli and Weatherglass Barometers clearly demonstrate changes in atmospheric pressure. Our Weather Science Kit includes everything your students need to explore basic weather phenomena such as the greenhouse effect, static electricity, air currents and more. Adopt a Pet Tornado to demonstrate vortices for students. And don't miss our conversation-starting Climate Change Mug-just add hot water and watch the polar icecaps melt!
